AUTOMATIC FILLING-REPLENISHING LOOM.

Specification of'Letters Patent. Patented Mal. 15, 1910.

Application filed October 19. 1909. Serial No. 523,489.

To, all whom it may concern."

Be it known that I, ()scr-sn JAMJLLE, a citizen of the lfnited States,and resident of Manchester, county of Hillsboro, State of New Hampshire,have invented an Improvement in Automatic F illing- Replenishing Looms,of which the following description, in connection with the accompanyingdrawing, is a specification, like characters on the drawing representinglike parts.

Looms of the Northrop type, in which the working shuttle is prbvidedautomatically with a fresh filling-carrier or bobbin when the fillingneeds to be replenished, are so constructed that the incoming, freshbobbin ejects the spent bobbin from the bottom of the shuttle andthrough a slot in the bottom of the shuttle-box in which slot thepicker-stick oscillates. To guide the ejected bobbin into a suitablereceptacle the cut away or slotted part of the lay has been providedwith an inclined chute having a part thereof upwardly extended beyondand cross-- ing the in'nerciid of the path of the pickerstick,substantially asshown and described in United States Patent No. 596,448,granted to J. ll. Northrop December 28, 1897.

Between the guide-chute and the outer end of the slot the picker-stickoscillates, and as filling-replenislnnent 'is effected when thepicker-stick is at the outer end of its stroke there is an open orexposed portion of the slot between the stick and the chute when abobbin will drop into such exposed part of the slot and jam thepicker-stick on its next inward stroke, causing more or less damage.

My present.invention has for its object the production of means to guardor substantially cover the part of the slot referred to when thepicker-stick at the outer end of its stroke, so that when a change orreplenishment 0f filling is effected the ejected bobbin cannot enter theslot. 1 have so arranged the guard that it is engaged by and moved outof the path of the picker-stick on the inward stroke of the latter andreleased shortly before the stick completes its outward stroke, so thatthe guard. returns automatically to its protective position. At suchtime the slot guard or protector is inclined downward and forward, sothat if the tip of an ejected bobbin strikes it it will'be directedforward in the general direction determined by the guide chute.

The novel features of my invention will i be fully described in thesubjoined specification and particularly pointed out. in the followingclaims.

Figure 1 is a. front elevation of one end of the-lay of a loom, at thereplenishing side, with the shuttle-box thereon and the guidechute, oneembodiment of my present invention being illustrated in connectiontherewith, the picker-stick being shown at the outer endof its stroke;Fig. 2 is a transverse section on the line 2-2, Fig. 1, looking towardthe left; Fig.3 is an inner end elevation of the movable guard, shown bydotted lines in position to permit the passage of the picker-stick.

The lay A, he shuttle-box B thereon at, the replenishing side of theloom, the raceplate C longitudinally slotted at l) for the picker-stickE and to permit the discharge of an ejected bobbin through the bottom ofthe shuttle, the cut-away or slotted part A chute F fixedly secured tothe front of the lay below the slot and having a part F upwardlyextended beyond and crossing the inner end of the path of thepicker-stick,

tector. Herein the guard is shown as; an elongated piece of plate-metal7, secured to or forming a part of the hub 6,'a'nd extended inward nearthe edge-0f the upwardly extended part F" of the chute, the guard beingcurved downward and forwardalong its upper edge, as at 8, at its outer.end, tocross the path of the picker-stick when the guard stick is at theouter end of its stroke, Fig. 1, it is at some distance from the camportion full lines Fig. 3, and covers or protects the picker-stick slotbeyond the'part F of the of the lay below the slot D, and theguidecrumed the hub 6 of the slot guard 01: prois in the position shownin Figs. 1 and 2, 7 and in full lines Fig. 3. -When the picker- 8 ofthe. guard, the latter then resting upon the u turned back 9 of thebracket 3, see

llf)

chute 1*. Should an ejected bobbin drop onto the inclined guard 7 itwill be thrown forward away from the lay, and into a suitablereceptacle, not shown, a diagonal, upright ledge 10 on the guardpreventing endwise movement of the bobbin toward the end of the lay. XVhen the picker-stick swings inward it engages the cam 8 and presses theguard 7 forward, the latter rocking on its fulcrum andthe picker-sticksweeps along behind the guard, holding the latter out of the way untilon its outward stroke the picker-stick leaves the guard, which dropsback of its own weight into guarding position. Stops 11 on the front ofthe bracket 3 limit forward movement of the guard, so that it cannotswing over its fulcrum.

In order to reduce. wear between the picker-stick and the guard I preferto back the latter with a facing 12 of leather, rawhide, or othersuitable material.

The dotted line position of the guard in Fig. 3 is that assumed whenengaged and swung forward by the picker-stick, and as will be manifestsuch position is maintained.

during the major portion of the movement of the picker-stick.

Having fully described my invention, what' I claim as new and desire tosecure by Letters Patent is 1. The combination, in a loom having a laylongitudinally slotted for the passage of a filling-carrier ejected fromthe shuttle, a ncker-stick reciprocatingin the slot, and a guidechutebeyond and crossing the inner cndof the picker-stick path, of meansgoverned by the yicker-stick to prevent the passage of anejectedfilling-carrier through the slot between the chute and picker-stick whenthe latter is at the outer end of its stroke.

' 2. The combination, in a loom having a lay longitudinally slotted forthe passage of a filling-carrierejected from the shuttle, a picker-stickreciprocating in the slot, and a guide-chute beyond and crossing theinner end of the picker-stick path, of a movable,

guard to close the slot beyond thechute when the picker-stick is at theouter end of its stroke, the picker-stick cooperating with the guard totemporarily move it out of the path of the stick.

' The combination, in a loom having a lay longitudinally slotted for thepassage of afilling-carrier ejected from-the shuttle, a picker-stickreciprocating in the slot, and a guide-chute beyond and'crossing theinner end ofthe picker-stick path, of a swinging guard pivotally mountedon the lay and extending laterally from the chute, to protect theexposed part of the slot from the entrance of a filling-carrier, a camon the guard to. cooperate intermittingly with the Witnesses:

picker-stick and move the guard forward out of the path of thepicker-stick, and means to limit swinging movement of the guard.

- i. In a loom, a longitudinally-slotted lay, 3

the picker-stick movable therein, and a fixed guide-chute on the lay andextended upward and across the inner end of the pathof the picker-stick,combined with a guard pivoted. on the lay and adapted to prevent theentrance of an ejected filling-carrier into the slot beyond the chute,and a cam on the uard to cooperate intermittingly with the picker-stickand effect movement of the guard out of the path of the picker-stick.

5. In a loom, a lay provided with a shuttle-box having alongitudinally-slotted bot tom for the discharge of a filling-carrierejected from the shuttle, said lay being slotted below the shuttle-box,a picker-stick movable in the slot, an inclined slot-protecting memberfixed on the lay at the inner end of and crossing the path of the pickerstick, a movable slot-protecting member pivoted on the lay to guard theslot beyond the fixed member, the movable member en tering the majorpart of the picker-stick path when the stick is at the outer-end of itsstroke, a stop to retain said movable member in inclined position atsuch time, means 611 themovable member to intermittingly cooperate withthe picker-stick and effect movement of the said member out of the pathof the picker-stick.

6. In a loom, a lay provided with a shuttle-box having alongitudinally-slotted bottom for the discharge of a filling-carrierejected from the shuttle, said lay being slotted below the shuttle-box,a picker stick movable in the slot, an inclined slot-protecting memberfixed on the layat the inner end of and crossing the path of thepickerstick, and automatically-movable means to protect the slot beyondsaid member when the picker-stick is at the outer end of its stroke andto move out of the path of the picker-stick on its inward stroke.

7 In a-loom, a lay slotted for the dis charge of a filling-carrier whenejected from the shuttle, a picker-stick movable in' the slotted part ofthe lay,a guide chute for the ejected filling-earner, extended beyondand crossing the i ner end of the path of the picker-stick, and means toprevent the passage of an ejected filling-carrier into the slot beyondthe'guide-chute.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
